From multimedia and activated-carbon filters to ultra, nano and micro-filtration membranes — the right barrier for every water-quality target.
Filtration is the backbone of clean water — whether polishing a supply, protecting an RO plant, or producing a specific quality on its own. CWG supplies and builds the full range: media filters for turbidity and iron, activated carbon for taste, odour and organics, and membrane filtration from micro to nano scale.
Media filters — multimedia, activated carbon, birm and green-sand — remove suspended solids, turbidity, iron, chlorine, taste, odour and organics as water passes through graded beds.
Membrane filtration works at a finer scale: micro- and ultra-filtration remove fine particles, colloids and bacteria, while nano-filtration reduces hardness and selected dissolved species — all without heavy chemistry.
CWG matches the technology and media to your water and target, as standalone treatment or as pre-treatment that protects and extends a downstream RO plant.
Water passes through a graded medium or membrane that captures particles by size — from coarse solids down to colloids and bacteria.
Multimedia beds trap suspended solids and turbidity.
Activated carbon removes chlorine, taste, odour and dissolved organics.
MF/UF membranes hold back fine particles, colloids and bacteria.
Nano-filtration reduces hardness and selected dissolved species where needed.
Cuts turbidity, suspended solids and colour reliably.
Clean feed extends membrane life and cuts fouling.
Membrane and nano-media stages work with little or no dosing.
Combine media and membrane stages to hit any spec.
Skid units with auto-backwash need little attention.
Long media life and simple operation keep costs down.
Multimedia and carbon beds for turbidity, iron, chlorine, taste and odour.
Membrane barriers for fine particles, colloids and bacteria without chemistry.
Selective removal of hardness and dissolved species between UF and RO.
From turbid surface water to iron-laden groundwater, Pakistani supplies need reliable filtration — both to deliver clean water directly and to protect the RO plants so many industries now depend on.
Since 1998, CWG Watch Water Technology has delivered advanced water & wastewater solutions across Pakistan — wastewater plants, RO, demineralization, softening, filtration, specialty chemicals and complete plant engineering. With decades of experience, international technology partnerships and a proven portfolio, we design customised water and wastewater treatment solutions built specifically for Pakistan’s industrial requirements.
Send us a water analysis and your target, and CWG will recommend the media or membrane filtration to match.
